ActionScript 3.0 :: Events / Execution Order - How To Sync
Aug 27, 2009
Scenario: I have a simple external class with one function that takes about 2sec to execute. It gets some data and put it into a global variable (using a special class for this). From the first frame on the timeline I call this function, and then right after I trace the global variable.
Problem: The trace is actually executed before the function in the external class has finished executing, so the output of the trace is undefined.
I have been trying to understand the way ActionScript's events are implemented, but I'm stuck.I know that AS is single threaded, which means that only one event handler will be executing at a time, and also means that handlers will be executed in a deterministic order*.For example, consider the following code:
1: var x = {executed: false}; 2: foo.addEventListener("execute", function(){ x.executed = true; }); 3: foo.dispatchEvent(new Event("execute"));
I have a chicken walking on the screen. The legs are separate movieclips nested. After a while I had the chicken walking rightwards, with hittest(there must be a better way) at the end of the stage he turned to the left and then again to the right after hitting the left barrier. I also got his right leg going up and down for a smoother walk. I did this with Tweener. But then the problems started. I didn't get the left leg also to move up and down.
The chicken got more and more crazy. And now he starts walking backwarsds instead of to the right, as I intended to, after publishing. Who has a better idea of letting this chicken walk or a good hint for functions to be executed when I want? Tweener is good, but maybe not for this? The chicken doesn't have to respond to a mouse action (maybe later), this is the code, for which the walking to the left apparently seems to be executed first....
Ok, a simple situation: say I have five fairly complicated functions on one frame. I define all my functions, what they do, etc. After all that, I call all five functions in a row like
I have an external as3 file for my timeline. I'm trying to download data from an xml file when a button is clicked. First, I have an xml loader. When it's finished loading, I assign the data to an xml variable. The trouble is, when I start this code from the onclick event, the code executes the xml loader, then the trace from onclick, then the assignment of the xml variable! So my data is always null! When I load the data from the constructor class, all is well. How can I make the execution take place in the proper order?
I have created an image gallery where each "slide" is an image loaded by one UILoader component. Everything works, except I noticed that as a user it is annoying to wait for each new slide to load.So, even with my limited knowledge of AS3, I decided to figure out a way to load the next upcoming image before the user requests itone for odd numbered slides, one for even numbered slides. That way, when the user is viewing a slide with an odd number in the first loader, the next image can be loaded into the second (currently invisible) loader and ready to go when requested button would simply toggle the visibility of these two loaders.
function nextButton(event:MouseEvent):void { imageNumber++;
I'm attempting to make a point and click game for a University assignment and I wondered if anyone could advise the best/easiest way to trigger events in a particular order. For instance, before the user can continue from one side of the screen to the other he has to click to flick a switch, lower a platform and lower a bridge...
As per the book, 'childAdd' event of parentcontainer should be triggered after triggering of 'PreInitialize' and 'Initialize' event of childcontianer while as per the program out put it seems otherwise.What I found in books is as below:
I have a flex application where on creationComplete i call a method in which i needed to load two XML files frm the server.only after which i need to proceed further..
Currently i am doing the following onCreationComplete = init();
private function init():void{//loading first XML urlReq = new URLRequest(PATH_FOR_XML1); urlLdr = new URLLoader(urlReq); urlLdr.addEventListener(Event.COMPLETE, doEvent);
I have a data grid and there's a method attached to clicking on any item in a row of the grid.Now, some of the items in the table row are also buttons. Each of these are associated with a different action.We only want one of these actions to be performed.[code]we have currently a member variable to track which selection was made and to ignore the the contents of the other method (the else portion of the method resets this value).Now, if the methods just happen to execute in a different order (or at the same time), the behavior will be unpredictable.Is the member variable flag the way to do this (it smells so bad)?
I have five simple equations that I need help converting to ActionScript. I'm making a small "calculator" that takes input from the user and displays a number representing the result of the equation. They're two sets of equations: 1) three-scenario fee calculator to compare the annual costs (X) of renting versus buying equipment; 2) comparison of two rental plans. The numbers entered need to stay the same - the alphabets represent what the user will input. The equations are as follows: Scenario 1:
X = ([A � F] / G) + H + I + J + (K x 12) + ([L / N] x M) Scenario 2: X = ([B � F] / G) + ([E x C] / G) + H + I + J + (K x 12) + ([L / N] x M)[code]....
I've looked at my resources at hand, but my brain just shuts down when I see numbers and letters representing numbers. I do speak three languages fluently, so I (think) I make up for it.how to properly assign the correct order of events (brackets first, etc) in ActionScript to reflect the equations above.
I need to know how I could do to interconnect different computers in order to share events in real time. For example, if I press some button I get a sound and I need that other who is using the same swf could mix it with anothers that can be generated by the same swf.
I am creating an order form for my flash site. I have never done this before in flash but I have in visual basic. I have a few questions:
1. Is assigning variable names to checkboxes and radio buttons the same as in visual basic? I mean i know that you probably assign them in the properties. ex..say i name a radio button 'radio1', to run a check in my actionscript whether radio1 was checked or not would it be something like if(radio1){}
2. After the person fills out the form I would like to have the results of the order sent to a pre-specified email adress in a certain format. What would be a good way to do this?
use CFC's via CF8 to interact with an Access db. In 1 screen of my Flash8 application, I have to update up to 7 rows in a table depending on whether a screen field was filled in and each of these updates is an identical activity. Ideally, my code might look something like this:
Just wanted to ask if there is any advantage for either using mouse click event or touch tap events, when writing apps for mobiles or tablets (for the iphone especially)?
I know that both of them should work fine, but in term of performance, is anyone better? Are there any things I should be aware of when choosing either?
By the way am using actionscript3 to implement the app.
I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.
I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).
I am having a problem cancelling the execution of a function. When I click on the first of my navigation buttons, I have a fade in tween and an image loader load an external image. If I click on the second navigation button befiore the function for the 1st button finishes, the 1st tween and image loader continue to finish while the tween and image loader function for the 2nd navigation button starts. Essentially, there is an overlap. Is there a way to tell the 2nd navigation button to stop all other functions before it starts its own function? I suspect it has something to do with stopImmediatePropagation, but I am unsure of how to put this into the function.
Is there any way to halt execution in ActionScript, such as a sleep() method? I know that there is a setTimeout() method, but setTimeout() just sets up an event for deferred execution.
I've a problem, I'm using an AdvancedDataGrid. It loads about 3000 records with about 20 columns. I constantly get Flex execution timeout because the grid executes a lot inside LayoutManager. How can I make it asyncronousely or faster at all?
I am building a Flex and PHP application in which I am providing users a Save results option, which will invoke the php service that generates the results file. I then have the FileReference.download (url) function with the url of the file generated. Problem here is the popup to save comes before the file is even generated in the server. So user will get the incomplete file as the file generation will take atleast 10-15 seconds.
printToFile.token = customerTyped.printToFile(customerArray,displayno); var filepath:String= "[URL]"+displayno+".txt"; var request:URLRequest = new URLRequest(filepath); var fileRef:FileReference = new FileReference(); fileRef.download(request);**
I think the function(service) call to PHP function customerTyped.printToFile(customerArray,displayno); does not wait for it to return and continues to execute the next statements asynchronously. How do I make the download dialog to wait from popping up until the printToFile php function is completed?
I'm querying Rotten Tomatoes' API for movies listed in an XML document. The problem I'm having is, whist iterating through and querying for each movie I'm hitting RT's API limit which, in turn, is throwing an IO error. Is there a way I can delay execution in a loop for about a second or so, to avoid this?
I'm designing a website with flash cs4 and actionscript3. Every section is made with a movieclip, which is faded in and out when a menu button is clicked.
I've noticed that the first time I click on a menu button, the fadein or fadeout effect of the corresponding section is not fluid (I'm using caurina tweener), but the section movieclip appears/disappears suddenly. I suppose it may be a buffering problem, because when I click the section button for the second time, the fadein and out is fluid.
